What exactly is a shell?..

Answer / Chetan Prakash

A shell is a user interface for interacting with an operating system using text-based commands. It provides services such as command interpretation, job control, file name expansion, variable assignments, and input/output redirection. The shell reads commands from the user, interprets them, and executes them on behalf of the user.
